Custom headers
Options

Linux / macOS

Standard curl command — works on Linux, macOS, and Windows (with curl.exe).

curl \
  'https://api.example.com/users'

PowerShell

Invoke-WebRequest — native PowerShell cmdlet (Windows PowerShell 5.1+ / PS 7+).

Invoke-WebRequest `
  -Method GET `
  -Uri "https://api.example.com/users"

Why this tool exists

Vultio cURL Generator builds ready-to-run HTTP commands from a form without needing to memorize curl flag syntax. Fill in the URL, method, headers, body, and auth options and get both a Linux curl command and a PowerShell Invoke-WebRequest command.

It is the counterpart to the cURL Converter: use the Converter when you have a cURL command and want code, and use the Generator when you want to build a cURL command from scratch.

Common use cases

  • Quickly build a cURL test for an API endpoint without looking up flag syntax.
  • Generate a PowerShell Invoke-WebRequest command for Windows automation scripts.
  • Build an authenticated POST request with JSON body to share with a colleague.
  • Create a cURL command template for API documentation or a README file.
  • Test different auth methods (Bearer, Basic Auth, API key) and compare the generated commands.

Example input / output

POST with Bearer token

Input

Method: POST · URL: https://api.example.com/users · Auth: Bearer abc123 · Body: {"name":"Alice"}

Output

curl -X POST 'https://api.example.com/users' \ -H 'Authorization: Bearer abc123' \ -H 'Content-Type: application/json' \ --data-raw '{"name":"Alice"}'

GET with API Key header

Input

Method: GET · URL: https://api.example.com/data · Auth: API Key (X-API-Key: sk-abc)

Output

curl 'https://api.example.com/data' \ -H 'X-API-Key: sk-abc'

Common errors

Command not found: curl

Cause: curl is not installed on the system, or is not on the PATH.

Fix: On Linux/macOS, install curl via your package manager (apt, brew). On Windows, curl.exe is included in Windows 10 1803+ at C:\Windows\System32\curl.exe.

SSL certificate problem in PowerShell

Cause: The server uses a self-signed or untrusted certificate.

Fix: Enable the "Skip SSL verification" option to add -SkipCertificateCheck to the Invoke-WebRequest command. Only use this in development environments.

Frequently asked questions

What is a cURL generator online?

A cURL generator lets you fill in HTTP request parameters — URL, method, headers, body, authentication — using a form, and produces a ready-to-run curl command without needing to memorize flag syntax.

What is the difference between the Linux and PowerShell output?

The Linux/macOS output uses standard curl syntax with backslash line continuations. The PowerShell output uses Invoke-WebRequest, the native PowerShell cmdlet, with backtick continuations and @{} header hashtables.

How do I use the generated command in PowerShell?

Copy the Invoke-WebRequest command and paste it directly into a PowerShell terminal (Windows PowerShell 5.1+ or PowerShell 7+). No extra tools needed — Invoke-WebRequest is built into PowerShell.

Can I add custom headers?

Yes. Use the Headers section to add any number of key-value header pairs. Common headers like Content-Type and Authorization are also set automatically when you choose a body type or auth method.

Is my data sent to a server?

No. The cURL command is generated entirely in your browser. None of your URL, credentials, or payload is transmitted anywhere.
